[Bug 376946] Re: Kernel Panic in Interrupt Handler on 8.04LTS/x86_64

[Albrecht Dreß]

Hi Jeremy:

Thanks a lot for your feedback.  Actually, when I reported the bug, I
had a crash of my server system about once a week, always somehow
related (IIRC) to sock_alloc_send_skb & friends.

As I didn't get any support and the situation was totally unacceptable
for our users, I decided to build my own kernel.  I now run 2.6.27.25 on
an otherwise unmodified 8.04 (except for a few self-built packages,
mainly from Lenny, including a win7-compliant samba, freeradius w/LDAP,
etc), and didn't see *any* crashes since then.

Maybe I should add that I ran a nfsv4 server on top of xfs partitions.
With the new self-compiled kernel, the nfs4 daemon crashed after ~2..3
hours and could not be re-activated, except after a reboot.  I switched
back to nfsv3, and now the system runs really stable.

As the box is a production server, I unfortunately cannot test the new
kernels.  I would be interested to know, though, if the combination 64
Bit kernel - NFSv4 - xfs is known to work with the upcoming LTS release
of Ubuntu.  NFSv3 isn't secure these days...

Thanks, Albrecht.
